The curvaceous Mad Men star selected a green midi dress with gold embroidery at the waist — a feminine, flattering number also loved by some of Scott’s other big fans, Penélope Cruz and Ellen Barkin (below). Hendricks finished the look with a gold clutch and pumps to highlight the metallic embellishments along the waistline and trim. And she radiated the bombshell confidence which she credited Scott’s designs for giving her.

Hendricks would know something about dressing like a knockout, thanks to seven seasons of playing her Mad Men alter ego, Joan Holloway. The actress said to expect to see a bit more skin as the show enters the late ’60s. “You know, hemlines are shifting,” she told PEOPLE on the red carpet. “You’re going to see Joan in some shorter skirts. I’ll say that.”

When it comes to her signature red hair that’s become synonymous with Joan, Hendricks said she might decided to try a new look after saying goodbye to the character. “Well, I’ve been this color for years and years and years,” she told PEOPLE when asked if we might see any hair changes. “But it’s funny you mention it. I was kind of thinking about maybe making a shift. Yeah, I’m thinking about it,” she said.
